IMPROVEMENT IN' STRAW-CUTTERS.

'lhe Schedule referred to in these Lettore Patent and making part 'of the. same.

To all whom. it may concern:

Be it known that I, NELSON OfEIL, of Purchase Line, in the county of Indiana and State of Pennsylvania, have invented a new and useful Improvement in Straw-Gutters; andI do'hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part oflhis specification.

The object of this invention -is to furnish a machine for cutting straw and other similar material for feed, which machine shall be cheap, durable, and convenient; and

It consists in the arrangement for changing or varying the length of the feed eut, as will be hereinafter more fully described.

In the drawing` Figurelrepreseut-s aview ofthe front end ofthe machine, showingr the knife, a portion of the upper feed-4 roller, and the mode'of operating the pawl-lever by means of which the feed is given.

Figure 2 is perspective side view, showing tbe pavfl-lever and the pawls, and the manner in which the pawls operate upon the feed-rollers.l

Similar letters of reference indicate corresponding parts.

A. is the cutter-box, ,which is of the usual form and size. t v B is the knife or cuttingeedge onv the lever C, whichlever has its fulcrum at the point D. f

E is the ,upper feed-roller, the journals of which work in vertical slots in the sides ot' the bo'X.

Each journal is forced downward by a spring, F, with a constant pressure, and ou one journal there is a ratchet-wheel, G.

The lower feed-roller is only allowed a revolving motion, and has a ratchet-wheel, H, on one of its journals.

I is the pawl-lever, which is in tbe form of a cross iu a horizontal position.

To the arms of the cross, pawls 'K and L arcattached, one of which pulls and the other pushes, in feeeding, as seen in the drawing.V

The fulcrum of the pawl-lever is at lil.

The `outer end of the lever passes through the vfront end of the frame, and works the pawls so as to give the desired feed when it is raised.

' N is a hook, made adjustable iu the cutter-lever C, as seen, by means of thercatch O. The end of the pawl-lever projects betweenthis hook and the lower edge of the cutter-lever, so that, in raising the hook, the end of the pawl-lever is raised, which gives the feed.

Then the knife descends the pawl-lever is forced down, which gives the pawls anew hold -upon the ratchets.

, The distance between the hooks N and the under edge of the lever C governs Vthe length of the feed.

`The pawl-lever is moved more or less, as the hoek is raised or lowered. v

This arrangement gives a positive motion for the feed, and the length of cutis varied in the most sim-- ple and effect-ive manner.

This is a very simple, cheap, and durable machine, and its advantages over more complicatedA and expensive straw-eutters will be apparent to all.

Having thus described my invention,

I claim as new and desire to secure by Let-ters Patent- 1. The adjustable book N, in combination with the cutter-lever "of a 'straw-cutter, substantially as and for the purposes described.

2. The cross or pawl-lever I, in combination with the hook NV and pawls K L, arranged andoperating substantially as and for the purposes, herein shown and described. NELSON ONEIL.
